Independent Rear Suspension

The independent rear suspension (IRS) upgrade is one of the best features you can add to improve your Roadster’s high-performance handling.

Composed of a Ford 8.8 center section and Ford hub carriers, the IRS uses poly bushings throughout. The lower control arms connect to the chassis with heim joints, providing complete adjustability and making alignment a breeze. The upper control arms mount to the chassis using two links that form a V shape. This provides for excellent strength and stability compared to a single tube upper control arm system. The unit is housed in a cage system which adds rigidity to the chassis as well as making the install a very straightforward operation. The IRS option price includes our $550 limited slip upgrade. The center section is completely rebuilt with the gear ratio of
your choice.

Our IRS unit is complete from rotor to rotor. This option can be ordered with new kit purchases or can be retrofitted to existing Hurricane solid axle kits.
